AIR FOUL-GAS EJ'ECTOR FOR GAS SYSTEMS.

Application flled April 26, 1926. Serial No. 1%,860.

This invention relates to means for separatlng air and non-condensiblegases from gas systems of refrlgeratlng plants uslng ammonia or carbondioxide, the eneral object of.

5 the invention being to provi e means whereby the condensible gaseswill be condensed in a chamber which is provided with a poppet valve forpermitting the air and non-condensible gases to escape, with means forreturning the condensed liquid to the system.

' Another object of the IIIVGIltlOll' is to provide a rotary valve whichis float operated for controlling the flow of the liquid from thecondenser chamber to the system.

This invention also consists in certain other features of constructionand in the combina tion and arrangement of the several parts, to behereinafter fully described, illustrated in theaccompanying drawings-andspecifically pointed out in the ap ended claims.

In describing my inventlon in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a longitudinal sectional view through the invention.

Figure '2 is a section on line 2-2 of Fig ure 1.

Figure 3 is a sectional view through the rotary valve, its float and aportion of the casing.

Figure 4 is a' section on line 4-4 of Figure 3.

In these views, 1 indicates a casing which is divided by a partition 2into a chamber A and a chamber B, the partition'being of greaterdiameter than the casing and the two arts of the casing having flanges 3which are olt-. ed to the projecting part-of the partition, as shown inFi ure 1. The partition is pro= vided withtlie perforations 4 forconnecting the two chambers together and wlth a central opening 5, andit is also provided with a passage 6 and a passage .7 which ass from thetop face of the partition throng the side edge thereof. A cylinder 8- ismounted on the partition and forms therewith a chamber C. A pi e 9,threaded in the hole 5, asses through t e top of the cylinder 8 anconnects the chamber- B with the topofchamber A. A bafile plate 10 issupported by the ,posts 11 from the top of the cylinder 8 and is spacedfrom the top of the chamber A. A valve casing 12 is connected with thetop of the chamber A by a pipe 13 and a poppet valve 14 is connectedwith one side of the valve casing and a gauge 15 is connected with theopposite side, the stem and handle of the valve in casing 12 being shownat 16. This valve controls the flow of fluid to the pop et valve 14 andthe gauge 15. The passage 7 is connected by a pipe 17 with the suctionline of a compressor of a refrigerating apparatus and this pipe containsa valve 18. A pipe 19 connects the passage 6 with the receiver of themachine, this pipe containing a valve 20 and a pipe line 21 connects thebottom of the chamber B with the pipe 19. This line 21 contains a checkvalve 22 and a valve 23, said valve 23 controlling a branch 24 which isprovided to drain the chamber-B. -The check valve prevents fluid abovethe valve from returning to the chamber B through'the-pipe 21. A rotaryvalve 25 has its outlet connected with the line 21 and is arranged inthe chamber B. This valve comprises a casin 26 which has an arc-shapedort 27 in eac side thereof and a oylindrica valve member 28 rotatablmounted in the casing. This member 28 as the ports 29 therein forregistering with the ports 27 and the port 30 for registering with theport 31 in the bottom of the casing-rand which is connected with theline 21. he stem 32 is rotatably mounted in the casing and has a flatprojection 33 thereon engaging a slot34 formed in one end of the valvemember 28 and the float 35 has its stem 36 fastened to an arm 37 whichis connected with the stem so that the movement of the float will becommunicated to the stem and the projection 33, engaging the slot 34,will cause the member 28 to move with the stem.- A guide 38 is providedfor the arm 37. An air and gas line 39, having a valve 40 therein,connects the bottom of the chamber B with the to s of the receivers andcondensers of the re rigeratin apparatus. A sight gauge 41 is providefor the chamber B and a-thermometer 42 is connected with the interior ofthe chamber A.

The valves of the sight gau e and valves 12 and 18 are open, valve 23 ajusted to close the branch 24 and valve 20 is opened to a slight 'extentto let some of the liquid from the receiver expand into the cooler orchamber C, thereb brin ing the temperature of the chamber 40 is openedto a slight extent so as to admit air and gas from the condensers orreceivers to a ow degree. Then valve into the chamber B. This air andgas will pass up through the perforations in the partition and throughthe pipe 9 into the chamber A and due to the low temperature of thischamber, the condensible gases in the mixture will be condensed and fallto the bottom of the chamber A-and through the perforations 4 into thechamber B. The air and non-condensible gases will pass to the top of thechamber A and flow around the baffle plate 10 and pass out through thepoppet valve 14 which is adjustable so that the valve can be set to openwhen the pressure in the chamber A reaches the desired point or degree.When the liquid in the chamber B reaches a level where it will raise thefloat 35, the valve member 28 will be turned so that its ports will bein register with the ports of the casing and thus the liquid will flowthrough the valve into the line 21 through which it will be drawnthrough passage 6 into'chamber C where the liquid is vaporized and thisva or will pass from this chamber through the pipe 43 intothe suctionline 17 Thus the air and foul or non-condensible gases will be ejectedfrom the system and the action will be automatic after the valves havebeen set.

It is thought from the foregoin description that the advantages andnovel eatures of my invention will be readil -apparent.

I desire it to be understoo that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such'changes fall within the scope of the appended claim.

What I claim is An air and gas ejector for a gas system of arefrigerating apparatus using ammonia or carbon dioxide comprising acasing, a partition therein dividing the same into upper and lowerchambers, a cylinder supported on the partition and arranged in theupper chamber, means for introducing a cooling medium into the cylinder,means for connecting the interior of the cylinder with the compressor ofthe refrigerating apparatus, a poppet valve connected with the upperchamber, means for introducing a mixture of non-condensible gas andvaporized refrigerant into I the lower chamber, means permittin themixture to pass into the upper chamber, a

float controlled rotary valve in the lower chamber for controlling thedischarge of the liquids of condensation and means for connectingthedischarge terior of the cylinder.

In testimony whereof I afiix'my signature. DANIEL C. SPRINGER.
